insists.

To all whom it may concern Be it known that I, CHARLFZJ r1. hionron,

a citizen of the United States, residing at \Vorcester, in the county of \Vorcester and to a settling tank in which a largeproportion of the waste mate-rial is retained while the partially cleared liquid is returned by the pump to the cutting tool. i

"lthas been customary to form the settling tank and pumping chamber as integral parts of-the machine, but objections" have been found to this method of construction. Under modern conditions of operation, thewaste material accumulates very rapidly in the settling tank and it is necessary to frequently empty and clean both the tank and the pump chamber. This operation requires a considerable amount of time during which the machine is necessarily inoperative.

It is the object of my invention to improve such conditions by providing a truck for the waste material which may be readily removed for dumping and cleaning. In its preferred form a partition separates the truck or tank into settling and pumping compartments ln the use of this truck it is assumed that a plurality of trucks will be 4 -.provided so "that one truck may be withd'rawnand anothersubstituted as soon as the g' ttling tank is filled to a point which neces-v sitates removal of the waste material.

in connection. with my improved truck I;

alsc provide a pump which may be readily raised to permit withdrawal of the truck 'without disconnecting the pump fromthe.

machine to which it is attached.

Further features. of my invention relate to the form of the tanln to means for positio'ning the tank relatively to the pump and themachine to which the pump s attached,

and to the handle provided iorinoving the truck.- Other features of myiinventionre ration roa WASTE MATERIAL."

late to certain arrangements and combinatlons of parts. hereinafter described and more particularly pointed out in the appendedw.

claims. 1 A preferred form of my invention shown in the drawings, in whichf Figure l is a embodying my improvements; k Fig. 2 is a side elevatiomof the truck shown inFig. 1 and also shows parts of a grinding machine with which the truck may be used;

P21143131 plan View of a truck Fig. 3 is a side elevation of the truck rei moved from the grinding machine and in dumping or cleaning position;

Fig. 4: is an end elevation of the pump showing the manner of its removal from operative position; 1 I I Fig. 5 is a detail sectional view of thei connection between the handle and the truck, taken along the line 5-5 in Fig. 3 I

Fig. 6 is an enlarged detail view of the means for positioning the truck relatively l to the machine; s Fig. 7 is an enlarged sectional view taken along the line 7-7 of Fig. 3 and showing the means for locking the handle in posi- Y tion on the truck; 1

Fig. 8 is a side elevation of the locking member which is secured to the handle, and

Fig. 9 is a sectional View of the locking plate which is secured to the tank, taken along the line 9-9 of'Fig. 7.

Referring to Figs. .1, 2 and 3, my improved truck comprises a tank or casing 10 preferably separated by a partition 11 into a settling chamber 12 and a pump chamber,

13. Thepartition 11 extends to a point;-

slightly below the top of the settling chamber 12 and thus permits over-flow of the liquid from the chamber 12 to the chamber;

13. A pair of wheels 1 1 are rotatable upon.

studs 15 (Fig. 5) secured tothe sides of the tank or casing 10. The wheels .14 support the truck near the outer end thereof, but

the load is so distributed that it is largely balanced about the center of the studs "15.

At its inner end the truck is provided with a projection 16 having a downwardly ex-ji tending cylindrical portion 17. A bracket 18 is secured in any convenient manner to? the frame of the grinding or other machine with which the truck is to be used. The

bracket. 18 has an outwardly projecting flange. shaped as shown in ljig. 6 to provide a flaring opening forgniding the cylindrical portlon 17 of the projection 16 to its desired position. In this position the shoulders of the projection 16 above the cylindrical portion 17 rest upon the bracket 18 and thus support the rear portion of the truck, while the portion 17 prevents accidental sidewise' displacement thereof.

In Fig. 2 I have indicated a grinding machine 20 having an extension 21 from which the cutting compound and waste material flows into the settling tank 12. I have also indicated a rotary pump 22 having spiral gears 23 and 24 or other suitable driving connections from the grinding machine, and

I have shown a pipe 25 which conveys the cutting compound back to the grinding wheel. The pump 22 is secured to the.

grinding machine by bolts 26 extending through curved slots 27 and permitting the pump to' be swung about the aXis of the gear 23. to a raised position in which it clears the rear wall of 'the truck. After the pump is thus raised the truck may be conveniently removed by means of the U-shaped handle 30.

The ends of the handle 30 are provided with heads 31 formed with elongated loops 32 which are slidable longitudinally and angularly movable on the hubs let of the wheels l-i. Special provision is made for locking the handle to the truck in either one of two positions. Each side portion of the handle is provided with a locking member 33 clamped to the handle by a screw 34 and provided with a spring-pressedplunger 35. Cooperatinglocking plates 36 are secured to the sides of the tank 10, one pair of plates being provided for positioning the handle as shown in Fig.2 and an additional pair of plates for positioning the handle as shown inFig. 3. Each plate 36 is deeply notched to receive a member 33 and is provided with a raised rib 37, as shown in Fig. 9.-

Assuming that the handle is to be shifted from the position shown in Fig. 2 to that shown in Fig. 3, the handle is raised and pulls the loops 32 along the hubs '14: untll the locking members 33 are moved out of the locking plates 36. The handle can then be swung to the desired position, after which it is pushed in until the locking members enter the notches or recesses between the raised side portions of the plates 36, and the plungers 35 pass across the ribs 37. The handle is thus held against sidewise movement by the plates'36, and the plungers 35 prevent accidental endwise movement.

When the truck is moved/to its upright or dumping position it is raised from its.

wheels and rests on the end portion 10 of the casing 10. The adJacent lower corner of the casing is rounded ofi so as to permit easy movement of the truck to the position of Fig. 3 and the dumping of the load is thus readily accomplished. \Vhile in this position the waste material in the settling tank can be readily removed and the entire device can be cleaned with little difficulty.

By the use of this truck the time ,lost during the removal of the waste material has been very largely reduced.

Having thus-described my invention it will be evident that further changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention as set forth in the claims. I do not wish therefore to be otherwise limited to the details herein disclosed but what I claim is 1. A truck for waste material comprising a casing, wheels supporting said casing near one end thereof, and means to locate and support the opposite end of said truck when in operative position.
